1960 Corvette Problems. Crankshaft Pulley?

Hello, first time posting.

I was driving my fathers 1960 Corvette on the highway, and while entering the highway and accelerating (gently, mind you... it is 45 years old) I hear a 'Bang Bang!" and a small circular object shot out from underneath my car. The tac gague dropped to 0, and the care IMMEDIATLY overheated. I made it to a gas station really quick, and looked, and the belt was off. So I continued to look, and It appears that there is a spot (where the crankshaft appears to come out of the front of the engine) that is bare, it has no pulley or anything on it. I was guessing that this is what came off, but I am not very good with cars, so it is only a guess...


Does this sound like a crankshaft pulley? How hard are they to replace if i was to try to do it myself? The exposed part of the crankshaft appered to be undamaged, but I am no expert.


Heres the other catch, I needed it for THIS FRIDAY (May 12th) for my Girlfriends Prom, and I would like to get it fixed by then if it is at all possible.


Thanks for your help
